It helps to draw a picture so you can visualize it better.
For the rug, since the area = 144, what two numbers multiplied give you 144? You might already know that 144 is a perfect square, so 12 x 12 = 144. 12 is the length of each side of the rug.
√144 = 12
12 + 3 = 15. (Add 3 because the rug only covers a portion of the floor. The entire floor = the length of the rug + the part that isn't covered)
15 x 15 = 225 ft squared (Multiply both sides of the floor to get the area.)
225 ft squared - 144 ft squared = 81 ft squared <-- your answer
Answer:
Domain of the function f(x) = cos x : ( - infinity , + infinity)
Step-by-step explanation:
Let the given function f(x) = cos x
We need to find the domain set of the given function f(x) = cos x
Domain is the set of all possible value of x for which the function f(x) is defined.
Now, as the given function f(x) is defined for all the real values of x.
Domain of the function f(x) = cos x : ( - infinity , + infinity)
Hence, Domain : ( -∞ , +∞ )
Also, the graph of the given function f(x) = cos x is attached below :
Now, form the graph also we can see the graph of given function f(x) = cos x can attain all the real values starting from -infinity to +infinity

x=1,x=3
Answer:
1) x=0.465
2) option A.
Step-by-step explanation:
1) The given equation is:
We rewrite this as logarithm to get:
The change of base formula is:
We apply the change of base formula on the RHS to get:
Group similar terms:
2)
From the graph, the logarithmic function approaches negative infinity as x approaches -6.
Therefore the vertical asymptote is x=-6
The graph touches the x-axis at x=-5, therefore the x-intercept is x=-5.
The correct answer is A.
